i have been gathering parts, modifying them and planning out my x25 blowback pistol it will be a blend of a pps43 and an ak, i am half way finished with modding the pps43 bolt to work with an akm boly carrier, i still need to cut the back off and turn it down to weld into a bolt carrier but it is haaaaaard steel lol. i'll post more pictures as i get to building.
here's a mock up
real mock up just in case i sbr it i put a stock next to it, i still need to shorten the pps43 shroud that i'm going to eld solid like an hk charge handle tube
bolt modification so far
